JOHN M. SANDERS, OF ATLANTA, GEORGIA.

PEA-HULLER.

Specification of Letters Patent.

Patented A pr. 2, 1.918.

Application filed February 5, 1916. Serial No. 77,183.

To all whom it may concern:

Be it knownthat 1, JOHN M. SANDERS, citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia. have invented certain new and useful Improvements in Pea-Hullers, of which the following is a specifi at-ion.

My present invention pertains to hullers for peas, beans and the like, and is designed more particularly as an improvement upon thehullcrs constituting the subjects of my Patents #561,616 of June 9, 1896, and #693,072 of l ebruary 11, 1902.

The object of this my latest invention, is the provision of a huller constructed with a view to efficiently hulling peas or beans, as the case may be, in such manner that the peas or beans are not cracked or otherwise injured, and then separating the hulls from the peas or beans without liability of choking or clogging and without the discharge of the hulls being attended by loss of peas or beans; the machine being positively cleared of hulls, and the delivery of all of the peas or beans to a receptacle being assured.

To the attainment of the foregoing, the invention consists in the peculiar construction, novel combinations and adaptation of parts as hereinafter described and definitely pointed out in the claims appended.

In the accompanying drawings, which are hereby made a part hereof:

Figure 1 is a side elevation of one side of the machine.

Fig. 2 is a vertical longitudinal section.

Fig. 3 is an elevation of the other side of p the machine.

Fig. 4 is a fragmentary top plan of the discharge spout, and

Fig. 5 is a top plan view of the foraminous Similar numerals of reference designate corresponding parts in all of the views of the drawings.

Obviously the casing 1 of my improved liuller may be of any form and material compatible with the present invention.

In the upper portion of the said casing a. hopper 2 is provided, the said hopper being connected by a throat 3 with the interior of a toothed concave l, in which is disposed a toothed cylinder 5. The teeth of the concave and cylinder are spaced in such manner as to shell the peas or beans without splitting, cracking or otherwise injuring the same.

From the lower portion of the concave 4 the peas or beans and their hulls pass through a depending conduit 6 to the bottom of a discharge spent 7 for hulls; the said spout being carried through the rear end of the casing and being provided at its rear end with an upwardly extending transverse flange or other abutment S, and being also provided beyond the casing with an upper wall 9 that terminates in a depending transverse flange or other abutment 10. The spout T is for the discharge of the bulk or major portion of the hulls under the action of a blast of air from a rotary fan 11, and the abutment or flange 8 serves to prevent any peas or beans that may be moved up the spent 7 from being driven out of the machine. Manifestly the hulls and chatl' will be blown over the flange 8 but the peas or beans will bring up against and be turned back by the flange, and will then gravitate through the spout to the lower end of the bottom thereof. The upper abutment or flange 10 serves to arrest and turn back any peas or beans that may ride upwardly on the hulls, and this without interfering with the free escape of the hulls and chaff between the two tlangcs 8 and 10.

The fan 11 is disposed in a casing 12, and from said casing a trunk 13 extends rearwardly to a point in front of the throat (3 and above the lower forward end of the bottom of the spout 7.

From the lower forward end of the bottom of spout 7, the peas or beans and portions of the hulls, chaff and other refuse, pass by gravity through an opening 14 and in rear of a curvilinear wall 15 and are deposited on a foraminous plate 16. This plate is capable of being withdrawn from the casing; the scheme being to use one plate when peas, particularly cow peas, are to be hullcd, and a plate having larger. apertures when beans such as velvet beans are to be shelled. The peas or beans, as the case may be. drop through the apertures of the plate 1.6 in company with a portion of the hulls and chaff, and fall upon an imperferate inclined support 17 by which the peas or beans alone are conducted to a box or other receptacle placed at the point indicated by 18 in Fig. 2. A discharge opening 18" for halls and other refuse is provided between the rear ends of the plate 16 and support 17, and a casing 19 containing a rotary fan 20 is connected through a trunk plate 16 be kept clear during the operationof the machine so as to enable the peas or beans to pass through said apertures to the support 17. l therefore provide above the plate 16 an endless drag 22. The said drag 22 comprises sp ocket or other-suitable belts 23 and spaced y verse bars 24 on which are steel teeth or spikes 25. The lower stretch of the drag is opposed to and parallel with the upper side of the foraminous plate 16, and the teeth or spikes .04) are disposed at approximate right angles to the plate, and hence in its rearward traverse the lower stretch of the drag will operate to arry such hulls, chaff and other refuse as find their way to the plate 16 out of the machine, thereby maintaining the plate 16 in a clear state for the passa e of peas or beans, obviating choking or clogging of the ma chine, and materially promoting the eiiiciency of the machine as a whole.

The general operation of the machine is clearly set forth in the foregoing, and it is therefore deemed unnecessary to reiterate the same.

The manner in which the working parts are preferably driven will be readily appreciated when it is stated that the shaft 30 of the cylinder 5 is provided at one side of the casing with a band pulley 31 for connection with a suitable motor, and is also provided with a sprocket gear 32. lhis sprocket, ear 32 is connected through a sprocket belt 33 with a sprocket gear 3 on the rear supporting shaft 5 of the drag 22, said shaft 35 and a forward idler shaft 36 being equipped with sprocket wheels 37 to engage the belts 23. From this it will be manifest that the drag 22 will be driven from the shaft 30. At the op osite side of the casing 1, with reference to the band pulley 31, the shaft 30 is pro vided with a band pulley dd, This pulley :0 is connected by a band 41 with pulley l2 on the shaft as of the fan 11 and also with a pulley 44 on the shaft 45 of the fan 20, and therefore said fans 11 and 20 will also be driven from the shaft 30.

The cylinder, fans and drag operate in the same manner on peas and beans. Experience has demonstrated, however, that when hulling peas the cylinder 5 should be speeded up to 300 to 350 revolutions per minute as against 250 to 275 revolutions per minute when beans, particularly velvet beans are to be hulled.

My novel huller,in the discretion of the manufacturer, may be constructed to rest on a stationary base, or may be mounted on a truck for convenient transportation from one point of use to another. I would also have it understood that without affecting my invention the sprocket belt 33 and the sprocket gear 34:, shown in Fig. 3, as well'as the sprocket belt shown in Fig. 1, may be ispensed with, in which event the drag 22 may be driven from the sprocket gear 32 through the medium of a short sprocket belt and a sprocket gear on the forward shaft 36 of the drag.

lilaving described my invention, what. I claim and desire to secure by Letters Patent, is:

l. huller comprising an inclined discharge spout for hulls and other refuse, provided with an upwardly and rearwardly eX- tending transverse abutment above its bottom wall at its outer and upper end and also provided with a top wall. that terminates at its upper end in a depending transverse abutment arranged below and in spaced relation to the first-named abutment and also spaced from the bottom wall of the spout, whereby chaff is enabled to pass to and through the space between the abutments and the abutments are enabled to turn back peas or beans, I means for supplying peas or beans and hulls to the inner portion of said spout, and means for forcing a blast of air outwardly through the spout.

2. A huller comprising a casing open at one end, hulling mechanism in the casing, a spout connected with the lower portion of the said mechanism and extending upwardly and outwardly in and beyond the casing, a fan chamber in communication with the inner end of the spout, a fan in said casing, a curved wall extending downwardly from the discharge end of the fan casing; the bottom wall of the said spout extending within said curved wall and underlying the lower wall of the fan casing, an inclined foraminous plate arranged to receive peas or beans and hulls from the lower portion of the said curved wall and extending through the open end of the casing, an inclined support below the said plate and open at its lower and up per ends, means for forcing air outwardly between the plate and the support, and means extending through the open end of the casing and constructed and arranged to move hulls and other refuse outwardly on the plate.

In testimony whereof I afliX my signature in presence of two witnesses.

JOHN M. SANDERS.
